PHONOGRAPH-REPRODUCER.

Specification of Letters fatent. Application filed April 15, 1908.Serial No. 427,224.

Patented Nov. 24, 1908.

To all whom it may crmcemf I Be it known that I, FRANK D. LEWIS, a icitizen of the United-States, and a resident i of Elizabeth, in thecounty of Union and State of New Jersey, have invented certain new anduseful Improvements in Phono- I graph-Reproducers, of which thefollowing 1 My invention relates to phonograph reproducers which areprovided with a pair of reproducin Styluses adapted to track records ofdi erent pitch, as, for example, records of one-hundred and two-hundredthreads perinch respectively, said styluses being mounted in a supportwhich may be moved or shifted so as to bring either of said stylusesinto and out of operative position with respect to the record surface asdesired; 'Such a reproducer is disclosed and broadly claimed in anapplication filed by Peter \Veber, March 26, 1908, Serial No.

Styluses of this character upon separate I levers which are separatelypivoted to a support which is rotatably mounted upon the floating weightof the reproducer.

According to the present invention, only one stylus lever is used andthe same is pivl oted directly to the floating weight in the usualmanner, and a support for both i stylus'es is movably mounted on orcarried l by one end of said lever.

| l l l In order that the mvention may be more fully understood,reference is hereby made to .the accompanyin drawing of which Figure 1is a side elevation, partly in section, of a phonograph reproducerconstructed in accordance with my invention; Fig. 2 is a plan view ofthe stylus lever of 1 Fig. 1, and Figs. 3 and 4 are side elevations ofmodified forms of stylus lever and stylus 1 sup ort.

T e reproducer shown comprises the usual sound box body 1 and diaphragm2 clamped E therein by the ring 3, the floating weight 4 g being pivotedat 5 to the block 6 which is 5 supported b the engagement of the screw 7l with the be y 1. There are one or more lugs 8 depending from theweight 4 and the stylus lever 9 is pivoted at or near its center One endof said lever 0 is conlink 10 to the center of the dim I nected by a lshoulders l holder provided with a lever, said stylus holder bemountedin a circular opening formed there-' in. The lower portion of the holder11 is formed with a pair of sockets, one of which receives a stylus 12suitable for operatin upon an ordinary record of one-hundred threads perinch, and the other socket rcceives a stylus 13 adapted to operate upona record having two-hundred threads per inch.

There is a pin 14 extending transversely through the st 'lus holder toenable the same to be readily turned through an angleof 180, themovement of the holder in each direction being limited by the engagementof a stop pin 15 with the body of the lever, the end of the lever beingslotted as shown at 16 to allow a-movement of the stop through an angleof 180. The stylus support is held in each of its operative positions byfrictional engagement with the st lus lever which is produced by theaction 0 a s ring washer 17 which surrounds the reduce upper end of thestylus holder and bears against the stylus lever and a nut or head 18secured to the said reduced end.

In the device of Fig. 3, the end of the lever 0 is reduced to form astud 19 and the stylus holder 11 is rotatable upon said stud, being heldin frictional engagement with the shoulder 20 of. the lever 9 by thespring washer 17 and nut 18 threaded on the end of the stud 19.

In Fig. 4, the stylus holder 11 is mounted upon a stud 21 extendingtransversely with respect to the lever 9 and is rotatable thereonthrough an angle of 180, its extreme posi-' tions being determined bythe engagement of 22, formed 'on the stylus holder, with the stop 23carriedtby the lever 9.

It will be noted that in all of the structures shown a simple rotarymovement of the stylus holder through an angle of 180, will convert thereproducer from an instrument suitable for operating upon records havingone-hundred threads per inch to one for o crating upon a recor and viceversa.

Having now-described my invention, what I claim is:

1. In a phonograph reproducer, the combination of the diaphragm andfloating weight, a lever pivoted to said weight ant connected to saiddiaphragm, and a stylus an of styluses and carried by said ing movableso as to bring either of said styluses into and out of operativeposition with respect to the record surface, substantially its et forth.

:2. In a phonograph l.'Ll)l.'Ul.lllCl the comhinution of the floatingweight, diaphragm, stylus lever pivoted to said weight and connected tosaid diaphragm, and a stylus holder provided With a plurality ofstyluses and I rotatably mounted upon said lever, substantially as setforth.

3. In a phonograph roproducer, the combination of the floating weight,diaphragm, 1 stylus lever pivoted to said weight and eonnee-ted to saiddiaphragm, and a stylus holder provided with a plurality of Styluses,

rotatahly gnounted upon said lever and frictionally held thereto,substantially as set l'orth.

4. In a phonograph reproducer, the com l inati0n of the floating weight,cliapl'iragni, stylus lever pivoted to said Weight and oon- .neoted tosaid diaphragm, a stylus holder provided with a plurality of styulsesand rotatahl moun ed upon said stylus, and means for limiting theangular movement of said stvlus holder in both directions, subgiantiallyas et forth.
